Snowpack Summary

New snow will fall onto a sun crust on south aspects, a temperature crust on all aspects below around 1700 m, and feathery surface hoar in sheltered and shaded areas. The new snow may not bond well to these surfaces.Below this, the snowpack is generally well-settled.

Problems

Wind Slabs

New snow is expected to fall with southwest winds. The highest amounts are expected in the south. This new snow may not bond well to underlying surfaces. Treat it with caution if enough snow accumulates, particularly if you notice slab properties.

Be careful with wind-loaded pockets, especially near ridge crests and roll-overs.Watch for signs of instability such as whumpfing, cracking, or recent avalanches.
